To all whom "it may concern: tion. Fig. 2. a side elevation of the same.

Be it known that we, AUeUs'rUs Finn)- ERICK Dawns, a subject of the Kingof England, residing at Second avenue, Manor Park, in the county ofEssex, England, manager, Pn'rsr. Cnnis'rrm OLSEN, a subject of the Kingof Denmark, residing at 1 Coverdale road, tllapliam Park, in the countyof Surrey, England, engineer, and ALBERT DAY, a subject of the liing ofEngland, resioiug at 85 Hewitt road, llarringay, N, London, in thecounty of Middlesex, England, chemical manufacturer, have invented newand useful Improvements in Machines for Feeding and Delivering Sheets ofPaper, of which the following is a specification.

This invention relates to improvements in apparatus for automaticallyfeeding, conveying, and delivering sheets or strips, hereafter termedsheets, of paper to the table or reciprocating carriers, or molds orpasting device all of which are hereafter termed and inc. ded in theterm table or other device,of, v,b:.1g forming. or pastor labeling.painting, or o her like hines.

The objects of this invention are, first, to provide means for enablinga sheet of paper to be fed singly and in regular order from a pile up afixed or adjustable incline, on to the table or other device; second, toautomatically adjust the bottom of the receptacle for the sheets to theincline and feeding mechanism; and third, to retain the sheets in thedesired position in the pile and to release them singly therefrom, andat the same time to remove any obstruction that would retard theeliicient workii'ig of the said retaining and separating mechanism.

The hereinafter described mechanism is mounted and fixed on separateframework independently of any of the above named machines, and it isarranged in any suitable position thereto that will permit of it beingdriven by, say, pulleys or belts, or chains and sprocket wheels, orshafts and gearing from a convenient rotating part of any such machines,as well as enabling it to deliver a sheet on to the said table or otherdevice.

We attain these objects by mechanism illustrated in the annexed sheetsof drawings in which Figure 1. is a sectional elevation of a machineconstructed according to this inven- Fig. 3. a side elevation of theopposite side of the machine to that shown at Fig. 2. Fig. t. a partfront and part sectional elevation of the machine. Fig. 5. a planlooking at the top.

Like parts in all the views are marked with similar letters ofreference.

On a suitable stand or pillar, or framework, hereafter termed stand a,is fixed a horizontal plate or table, hereafter termed a plate 7). Onthe said plate Z) is fixed,- adjustahly or otherwise,at a. suitabledistance apart, the two cheeks or sides 0, (Z, of the framework of thefeeding mechanism. The said cheeks or sides of the framework are made ofany suitable size, depth, and shape and provision is made in them forthe reception of the drawing rollers c, f, the sheets g/ to beautomatically fed arranged in a pile, the adjustable bottom for thesheets, and the means,to be hereafter described for retaining them inposition, and for feeding them up a fixed or adjustable incline 2' tothe drawing rollers. The drawing rollers e, 7', may, or may not, havesuitably grooved or recessed portions as shown at j, Fig. 5, and may beprovided with one or more projecting rings 7.;, Z, for drawing thesheets between them. That is to say, the top roller 0 is provided with aring 70 at or about its center, and the bottom roller with three (moreor less) rings Z, having a recessed portion between them.

The rollers c, f, are suitably geared together by spur wheels 11, 0, aswell as to a driving shaft p by means of a spur wheel (1 gearing with apinion 1 mounted upon a spindle or shaft 8 which is geared by spur wheelI? to the spur wheel a. on the shaft of the roller 0. The driving shaftreceives a rotary motion from a moving part, say, of a bag forming, orother inaohine by any of the hereinbefore mentioned means, as forexample, say, by belt it working over flanged pulley 0) fixed upon thedriving shaft 29.

The incline 2' for directing the sheet from the pile to the drawingrollers is fixed as at Fig. 1. WVhen the incline z is a fixture it issecured to the sides 0 (Z by bolts so as to be at a predetermined angleto the rollers e f as well as to the plate It. If desired the lowest endor edge of the incline 2' is arranged to be at a suitable distance fromthe upper edge of the said plate. lVhen this is done a vertical andtransverse plate 12 is provided to prevent the sheets passing under theincline. At Figs. 1 to 5 the incline is shown to extend the fulldistance between the sides 0 (Z. The box or portion of the framework 20in which the pile g of paper is placed is shaped according to thecontour of the sheets to be fed. The box 10 is provided with a movablebottom it provided with a boss at, in which is fitted and secured theupper end of a vertical screw shaft y arranged to pass through boss 2formed on the underside of plate 6. Below the boss 2 is mounted a bevelwheel 1 on the screw shaft y. The boss of the bevel wheel 1 forms a nutfor the screw thread portion of the shaft y.

The bevel wheel 1 is mounted on the screw shaft 1 in the space betweenthe boss .2 and the vertical boss of a bracket 2. The screw shaft ywhich has a screw thread out thereon for the major portion of itslength, is made to pass through both the bosses 2 and 2, as shown atFig. st. A second bevel wheel 3 is made to gear with bevel wheel 1. Thewheel 3 is fixed upon a spindle or shaft mounted horizontally in thebearing 5 forming part of bracket 2 which is fixed to the stand a. Thebracket 2 is thus provided with two bosses or bearings, one a verticalboss and the other a horizontal one. On the outer end of the shaft isfixed a ratchet wheel 6, and between it and the bearing 5, a lever 7 ismounted loosely upon the said shaft. The upper end of the lever 7 isconnected by an adjustable connecting rod 8 to a double ended lever 9fulcrumed to the side (Z. On the pin 10 that attaches the bifurcated endof the connecting rod 8 to lever 7 1s mounted a pawl 11 adapted toengage with the teeth of the ratchet wheel 6, by which an intermittentrotary motion is imparted to the shaft 4 and bevel wheels 1, 3', forraising and lowering the adjustable bot tom 72. The bottom 71. isarranged to slide up and down between the guides 12, which also aids inkeeping the pile of sheets f/ in position. The movable bottom may, inthe first instance be raised to and from its work by hand or power.

To the outer face of the side (Z is castor fixed at its upper end guides13, for a slide 1%, provided with tapering sides to fit the guides. Theouter end of the lever 9 is connected by a link 15 to the slide 14.. Theupper end of the said slide is enlarged and provided with a rectangularshaped hole adapted to receive an adjustable horizontal bar 16. Theouter end of the bar 16 is enlarged to form a semicircular boss with afiat side (Fig. 8) in which is pendently mounted and fixed the presserbar 17 by a set screw (not shown in the drawings) or other suitablemeans. The presser bar 17 rests upon the top of the pile of sheets g. Ifso desired,but not necessarily so,the presser bar 17 and horizontal bar16 may be made in one instead of two portions.

To the horizontal bar 16 is fixed,adjustably or otherwise,-a nnmber,say,two,of bosses which form bearings 24, or the bearings 2 1 form part ofthe bar 16 and project therefrom above and below this enlarged end asshown at Figs. 7 and 8. In the bearings 24 a vertical rod 18 is made toslide. The vertical rod 18 is weighted at 20 and its lower end is armedor has fixed thereto a needle or pin or knife 21 which passes throughtwo or more sheets of paper for pre venting more than one sheet beingremoved at one time from the pile. movement of the rod 18 is regulatedby an adjustable collar 22, which is mounted upon the rod 18, above theupper bearing 24:. At certain portions of the intermittent falling ofthe presser bar 17 the vertical rod 18 as a rule remains stationary withthe pin in the pile; but if desired provision may be made for raising itwhen the surface of one of the bearings 24 comes in contact with the adjustable collar 22. An adjustable or other pin 23 is fixed or mountedupon the vertical rod 18 at a distance from the collar 22, whereby theneedle 21 may be pressed into the paper when the lower bearing 21 comesin contact with the pin 23.

An intermittent reciprocating motion is imparted to the slide 1 1 bymeans of a cam 25, mounted upon the driving shaft p arranged to act upona runner 26 on the short end of lever 9 and by the opposite end of thesame lever being connected by link 15 to the slide. The presser bar isslightly raised while the feed wheel 28 is drawing a sheet away from pinor needle 21 and causing it to travel up the incline. Afterward thepresser bar descends upon the pile 9. Simultaneously with thereciprocation of the slide 1% the adjustable bottom 71 is caused to beintermittently moved in an upward direction, owing to the pawl 11 andlever 7 be ing connected by rod 8 to the lever 9 upon which the cam 25operates. On the rod 8 being moved downward the pawl 11 by itsengagement with the teeth of the ratchetwheel 6 imparts an intermittentrotary mo tion to the shaft 4 and bevel wheels 1 and 3 for raising'thescrew shaft y and adjustable bottom it. This upward movement of theshaft 3 is obtained by arranging the boss of the bevel wheel 1 to act asa rotary nut for the screw threaded portion of the said shaft. Theadjustable bottom it is returned to its normal position,say, its lowestposition be- The downward V tween the guides 12 by means of a fixed orremovable handle 2T,shown at Fig. at,- which is employed for rotatingthe shaft 4: and bevel wheels 1 and 3 when the pawl 11 is disengagedfrom the teeth of the ratchet wheel (5.

The sheets of paper 9 are fed singly from the pile to the rollers 0,7",by a feed wheel 2S,with or without a rubber or other elastic tire,lixedupon a horizontal spindle or short shaft 29. The spindle 29 is mountedin axial bearings at the lower end of a swinging carrier 30. Theswinging carrier 30 is bifurcated at each end in which bifurcations areformed axial bearings. The upper end of the c rrier is mounted to swingfreely upon the driving shaft 7) so that the periphery of the feed wheel23 will rest upon and move down 'ard with the pile of sheets a. A r tarymotion is imparted from the driving shaft ,7) to the feed wheel E28 bymeans of two pairs of b vel wheels 31, 32, mounted respectively upon thedriving shaft horizontal spindle 29, and upon opposite ends of anintermediate spindle or shortshaft 33 carried by the carrier 30 at orabout a right angle to the driving shaft and horizontal spindle.

The feed wheel 28 is arranged by its rotation to draw the sheet of paperup the in cline 2' and thus awayfrom the said pin 21. If required, themovable bottom A may be plugged at 3st (Fig. 1) with hard wood at thepoint where the pin 21 is liable to come in contact with it. In order toremove any paper that might adhere to the pin 21 after a sheet has oeenfed finvard, to the vertica rod 18 is pivoted a swinging lever 35 (Figs.9 and 10) provided with an enlarged free end 36 for clearing the pointof the pin 21 from any incumln'ance. The enlarged end. 36 of the saidswinging lever is timed to pass behind the pin each time the presser bar17 is raised by a pin or projection 37 on the former acting upon aprojection or arm 38,or a slot hole therein,fixed to or forming part ofthe rear of the swinging lever The pin or projection 37 which acts uponthe rear portion 38 of the lever 35 moves its enlarged front portionforward for removing any obstruction or paper that may have been leftadhering to the pin or knife 21.

Yhen the machine is employed for feeding unpasted sheets of paper to,say, printing or bag forming machines, then each sheet of paper is fedup the incline i and passes between tne rollers 7, as at Fig. 1, and itis delivered directly on to, say, the "able of the machine.

' he action of the machine is as follows: T he sheets of paper areplaced in a pile with in the box portion a: of the framework and uponthe adjustable bottom A. The feed wheel 28 is then placed upon the topof t'ne pile. he pin 21 is then arranged in position. lVhen a rotarymotion ii imparted to the feed roller 28, the latter by its frictional.contact with the pile first separates a sheet by causing it to travelforward away from the pin 2t a nd. afteri 'ard up the incline i to andbetween the rollers c j by which it is drawn fol-ware and passed on tothe table of the printing or bag forming, or other machine.Simultaneously with the fe ding of a sheet the lever 9 will be actedupon by am 25 for raising the slide ll and pre bar 17, during the timethe adjustable tom it is being raised by the screw shaft 3/ when actedupon by bevel wheels 1 and :3, operated by shaft 4-, ratchet wheel (3,pawl 11, lever T, and coimecting rod 8 which attached to the lever 9, a

On the descent oi the slide ll and rcsser l 1? t ie enlarged end 3b oflever 35 will be moved forward for clearing away any paper adhering tothe point of the pin 21.

We are aware that prior to our invention, machines have been arrangedwith separating and feeding devices, 'n which a sloping surface or ridgeand a rocking arni carrying a feed wheel have formed important features,also that holding pins and rollers have been made to act upon the pilefrom which a sheet to be fed has been torn. e therefore do not claimsuch a combination broadly.
